Windows 2003 shows 4GB of RAM against actual of 8GB.

    Pertanyaan

  • Dear All,

    Just recently I have upgraded my terminal server from 4 GB RAM to 8 GB RAM but the windows 2003 standard edition installed in it shows on 4 GB of RAM. I had searched in Google to get a solution for this and from there I found one solution mentioning added the /PAE value in the system startup file. But this also did not work.

    In Bios it is detecting 8 GB of RAM but not in Windows. Can anybody help me in resolving this?

    Thanks & Regards,
    Jimit Shah.

  • This is a license issue, not a technical issue.
    Windows Server 2003 Standard Edition x86 is limited to 4GB RAM.

    Your options are to either:

    • Install Windows Server 2003 (R2) Enterprise Edition x86, or
    • Install Windows Server 2008 (R2) Standard Edition x64, or
    • Install Windows Server 2008 Enterprise Edition x86, or
    • Install Windows Server 2008 (R2) Enterprise Edition x64

  • Hi,

     

    No. Since the maximal size of the memory Windows Server 2003 Standard 32bit can support is 4GB, you have no way to use more than 4GB.

  • Dear Sander,

    Thanks for your reply.

    But right now my application is running on this server and hence cannot think of formatting and reinstalling the OS. Also I am not pretty sure weather the application would be compatible with Windows 2008 or now.

    Can I get some alternate solution to this?

    Thanks & Regards,

  • Hi,

     

    This is by design and no alternative solution. To use more than 4GB memory, you have to upgrade your system to a higher version or install a 64bit system.

  • Hi,

    But is there any possibility that I can use some PAE command in the boot.ini file and that may solve this problem at least for some time so that meanwhile I will check its compatibility with the 64 bit OS or Windows 2008.

    Thanks & Regards,

  • Is it possible to upgrade the server from Standard to Enterprise without blowing away what is on the system currently?

    Unfortunately not.

    This functionality is called "Windows Anytime Upgrade" and was introduced with Windows Vista and Windows Server 2008. This functionality allows to upgrade to a more elaborate Windows SKU by simple entering the product key for the new version and a reboot. (might take 10 minutes in total)

    For Windows Server 2003 you will need to install Windows Server 2003 (R2) Enterprise Edition over the current Windows Server 2003 (R2) Standard Edition installation and reinstall the current applications.

    No you will not be able to upgrade using the anytime upgrade. This is snippet from the "Windows Anytime Upgrade FAQ".


    Can I upgrade both 32-bit versions and 64-bit versions of Windows 7 with Windows Anytime Upgrade?

    Yes, you can use Windows Anytime Upgrade to upgrade a 32-bit version to a 32-bit version or from a 64-bit version to a 64-bit version of Windows 7. However, WindowsAnytime Upgrade can't upgrade a 32-bit version to a 64-bit version of Windows 7 or a 64-bit version to a 32-bit version of Windows 7.

  • Strange thing is the following article (from MSDN thingy).

    It claims that 2003 std w SP2 installed could address to 32 GB if PAE enabled.

    Unfortunately i cannot get it to work so it could be a miswritten doc.

    I have read the document thoroughly.
    The /PAE switch is only available in 32bit (x86) versions of Windows. Using this switch in the 32bit version of Windows Server 2003 Standard (regardless of ServicePacklevel) will not result in going beyond the licensing boundary of 4GB.

    The 64bit version of Windows Server 2003 is capable of addressing up to 32GB of memory. As I stated in my first reply, switching to the 64bit version is an option to address more than 4GB with Windows Server 2003 Standard.

  • Hello,

    In addition to setting the switch,

    Your processor has to support this.

    Your chipset has to support this.

    Your firmware settings have to support this and be properly set to make it available.

  • Dear Sander,

    I have similar issue and I am using Windows 2003 Enterprise 32bit which is installed on 64bit hardware.

    I have an Oracle Database installed on the same server and Oracle process is not able to take more than 1.5GB of memory.

    Is there any solution by which Oracle could use 64GB physical memory?

    Thanks
